I don't have kids but I have friends with kids and I have seen various approaches to feeding those little beasts. Some approaches save more time than others. I would recommend making large freezable meals over the weekend that can be heated up in the microwave for meals during the week.
Pot roasts cook themselves, meat loaf is easy, lasagna is simple and tastes great with some texas toast in the toaster oven and a fresh salad.
Don't spend 2 hours cooking every night like some people do.
Don't mow the lawn or do deep house cleaning or pressure washing. Pay someone to do that.
Stop wasting time on the internet, going to yard sales, watching tv, talking on the phone with friends about your day etc.
My hobby is studying now and I keep thinking of the end goal so thats what gets me through it.
I have no idea how it is to raise kids while doing this stuff so I can only imagine.
